My wife serves as historian for a local chapter of a women's group. She uses the binders to organize and protect sheet protectors to conserve and protect the historical items.
I thought this was exactly what I wanted/needed a binder which I could label from the outside for easy reference. The front cover of the binder was fine with a clear sheet behind which I slid the custom cover. The side panel however did not contain a sheet behind which I could slide an identification.
The clear outer cover is a plus because I can make a cover to slide in between the plastic see through cover and the notebook. The binder holds several sheets of paper.
These plastic binders will do the job if needed but the pricing is kind of ridiculous. Perhaps this is what happens when the local competitor goes out of business in the area.
